 In a three foot tube the water is colourless. It is agreeable to 

 the taste, and its continued use is followed by no ill effects. An 

 attempt was made to estimate the free carbonic acid by filling some 

 bottles completely at the spring, but in every instance I believe 

 some "free acid" escaped. When the water reached the laboratory 

 it contained two hundred and eighty-nine cubic inches of gas to 

 the gallon. As the water rises in the spring it has a temperature 

 of 53° F., the temperature of the air at the same time being 60° F.
